The pinion is itself rotated by a gea-r Wheel 10 loosely mounted. on a slm-ft 11 and actuated by means hereinafter de scribed so as to turn in the direction of the arrow` .in Fig. 2 under the -ininence of a Jforce constantly exerted. 4Near 8 the typewheel shaft 'i' carries an escap ment whee1'12 having staggered teeth on its opposite sides, as clearly shown in Fig. 2. This scape wheel is controlled by a vertical armature tongue 13, supported at its lower end by a lat spring 14, and Vibratinr 1ater ally between screw stops 15, by which the extent of the swing of smid touffue is regulated. The ton e is vibrated 'hf a. polarized magnet 16 lai-ing magnet coils 17, 18, the whole being secured in position by a tie-plate 19 which bears against the per marient magnet 20 and which is fastened by screws 21 to a plate 22 on the frames l, 2. By loosening the screws 21 the magnet may be adjusted vertically and laterally to bring the ton ne 13 into proper relation to the Scape-wieel. The tongue stands normally in engagement with a tooth, on the scape wheel, but for the` sake of clearness the two are shown disengaged in Fig'. 3. From the foregoing it wil be seen that as the tongue swings to ri ht or lett, as the case may be, under the ininenee of the polarized magnet the tooth with which the tongue is in ento tur desired tn print ma t. 'plfession polnt-q V:slight 'rotary movement, A i 'wax-das mayv be necessary to. bring the desired type into position .for pr1nt1ng,and for this pnrposethe following' uistrumentalltles Iare provided. On the typewheel shaft 7 '1s a star wheel 23 havin teeth sufficient 1n number and so arranged that the spaces or notches between the teeth are 1n register with the characters onthe printingwheel 5; *f} 1`1' '-ot l1er1wor. ljwith ,thetype; 25. "="r.anged that'whn .the 'sta-r wheel is in normal ".j-,'pos1tion, that is,'when`a space 'onthe typewheelstands Vopposite 'the 'printing point, the apex 'of the finger will be 'opposite a ltooth onthe star wheel. If now the linger be raised or lowered and shifted 'toward the star wheel it is clear that the apex of the finger, entering a notch on the wheel, will cause the wheei (and shaft 7) to turn slightly in one direction or the other according as the finger were first moved above or below the tooth,-`such sli ht movement of the star wheel and shaft` eing permitted by the yielding connection between shaft 7 and 4P pinion `8 before described. Thus when a fselected pair of characters has been brought to the' printing point either character of the pair may be brought to the printing point by proper adjustment and movement of the shifting finger. This linger also serves to center or justify the typen-heel as will be readily understood. For the pur ose of shifting or adjusting the finger to rin it into position to engage one or the ot cr notch as desired, it is provided with a longitudinal slot or opening in which is an elon gated member 25, plvoted at its lower end to swing transversely in its slot and having its upper end inted as shown. Extending through the s ot in the finger Q4, at the upper end thereof, is a pin 26, fixed to the plate 2, while extending from the adjusting member 25 is a. pin 27 engaged by the forked end of an arm 28 which extends down to a shaft 29, at the bottom of the machine, on which shaft the said arm is rigidly mounted. It will now be clear that by rocking the shaft 29 the shifting or adjusting member 25 will be swung by the forked arm 28 in 65 one direction or the other; hence when the "shifiig'-lifrligi ,94 iscariied toward the star wli'ecithe 'ointefl end of the shifting meml Thdftypewhcel is then lgiven l 'backward 4or fon' 05 .wl strike .on one side or the other joking" liefshaft-*2li.g'lt-isprovide at its {en ds with 'armatnres`31,32, (Figs. 3 and 4) lying 'between polarized magnets 33, 34, so that by suitable energinat-ion of these mag Smets, as hereinafter described, the shaft will be rocked in one direction or the other as desired. V"The shifting and justifying finger Qiis pivoted'at 30, as before stated, on the lower end of an arm 35, the other end of which is rigidly mounted on a short shaft 36 journaled in the plates 1, 2, at the top of the machine. Fast to the same shaft is a rearwardly extending arm 37 constituting thea-rmatnreof a magnet, which, as will be explained Ahereafter, 'also vfurnishes the power Ifor elfecting the letter-spacing. Energization of-'this magnet will there-'fore advance the shifting finger and throw the type wheel forward or back, as before described.

The mechanism for rotating the gear 10, which, it will be remembered, engages the pinion 8 to revolve the type wheel shaft 7, is shown in Figs. 1 and 2. On the shaft 11 is a coilv spring 39 at one end engaging a pin 40 on the gear and at the other end engaging the shaft frictionally so as to prevent overwinding. Adjacent to the gear but :tast on the shaft outside of the plate 1 is a ratchet wheel 41 engaged by a pawl d2 pivoted on the lower end of an arm 43 extending downwardly and forwardly from the shaft 36. Said pawl is yieldngly held in engagement with its ratchet by a coil spring by a fine-toothed ratchet 44 engaged by a pawl 45 loosely mounted on the shaft 36. This finctoothcd ratchet is made heavy enough to serve as a fly-wheel or momentum device. so that the impulse given to it by the vigorous upward stroke of the pawl 42 will cause it to turn farther than would otherwise he the ease and so have a greater winding eif'ect on the spring 39. Y

The printing is effected by a. )laten or printing bar 46 round or flattened slightly on the printing side, as desired, mounted on angular supports, one of which is shown at 47 in Fig. 4, pvoted at their forward ends to the frames 2, 3. On the support adj ncent validly extending -velfm flower emi-:1:11V- ,:shaped-fi laterali through'an'upe fur Y through the@ arm 451Mo fin. underlying Stud f-is a screw 55,by which the said arm, be ing of spring metal, can be 'shifted toward -'or from the. ratchet 50.

The slot being so arran ed that when the two armatures are raise the pin will be in contact with the bottom of the slot, it is clear that when both magnets are denergized the upward movementof the rod wlll raise armature 59 to its initial position, as shown in Fig. 2. It is'also evident that magnet 38 can draw down its armature without affecting armature 59.

As hereinafter explained, and for the purpose of 4making the machine as rapid as possible in operation, the magnets 33, 3i, 38 1nd 58 are intended to be energized simultaneously; but it is clear that their armatures should not be actuated at the same inetant. That is, armatures 31, 32, which set the shift-ing member (Fig. 4) should precedegarmature 37, which actuates the shifting and justifying finger 24; while the lastnecessary, to allowfor wear oir-.the finger.

If now magnet 66 be energized the shaft 64 will be rocked and thus cause the lower portion of the stop to throw the Enger off of the shoulder, as illustrated in. Fig. in which the armature is shown drawn back to its rear- ,ward .position ,bythe magnet 66. The -niagnetfB canlliwdepres's its armatureand effeet the' printing. -Itis also intended that magnet 66 beenergize'd'at the saine time-as magnets-,38 yand 5S, but evident-ly the rst named shouldnotactnate its armature until 'nlagnet'SS has acted, .as'otherwise the print.-

ing might be effected before the type wheel was set. Provision is therefore made' as follows for insuring Athe operation of magnet 66 after magnet 38. On the shaftv 64,

adjacent to the stop 63, is an arm 67 extending into rearward engagement with an extension 68 of the arm 43, which, it, wiil be remembered, is fastto the shaft- 36 which carries the armature 37. Hence if the magnet 66 were to not before magnet 38 it would have to raise the arm 43; butthe spring 43,

added to the tension of the 'spring 69 which'- retracts the armature 65, puts too great a load on the arm G7, for the magnet 66 to more unaided, and the result is that al` though current is owing through both niagnets simultaneously, magnet- 66 cannot act to release the printing mechanism until magnet 3S has acted and caused the typewheel to be set.

For shifting the tylmwheelV along the shaft 7 to effect the. letter spacing the following devices are provided. On a bar or rail 70, below the shaft 7 (Fig. 3) and fixed in frames 2, 3, is a hub 71, said bar being triangular in cross Section or otherwise formed to )erinit the hnb to slide.I but not to rotate. Jxtending in opposite directions from the hub, parallel with the rail, are two exible cords 72, 73 passing' over pulleys -L, 75 and winding in opposite directions on two winding' drums 76, 77, xcd on a shaft 78. It will therefore be seen that as the shaft.- is rotated to wind the cord 73 on its drum the huh drawn to the right (as viewed in Fig. 3), while rotation of the shaft in the opposite direction winds up l 3 8, the typewheel will be shifted tothe right i tooth onthe ratchetj' When the magnet'SS 'its initial' position, depresses the 'pawl 'S2 and so rotates the sha-ft 78, by' a space corthey; -cl irection: necessary to-Lnind. cord 573,011 i will 'carry the 'typen/heel one'jletter-space to 1 'lt-nre 37 tofit's' initial :posit-ion it will be seen the shaft 7S -(Fig. 3) is a pinionand around the shaft 1s a. coil sprmg 86, at one .the other end engaging a pin 88 on a collar 89 rigidly mounted on the shaft.

The paw-1 82 is heldin yielding engagement with its ratchet by a spring 84 fixed to the arm 83, as shown in Fi@ 5 The 'return of the typewheel to its initial position at the left is effected by the fclloning mechanism. Loosely mounted on en d engaging a pin S7 on the pinion and aton a fixed shaft 91, which latter is surrounded'by acoil spring engaging a pin 93 on the gear and fast to a stud 9i on the shaft. The springs S6, and 92 are arranged so as to be Wound up by the rotation of the ratchet 81 and shaft 7S; the reverse movement or nnn'inding of the springs, during the retract-ion of pan-'l 82, being prevented by a holding panfl 95 engaging the ratchet. It will therefore be clear that-` if both pan-'ls SQ and 95 are disengaged from the ratchet the i springs, previously wound up as described. i will rotate shaft- 7 8 in the opposite f lirection, thereby winding mrd 72 on the drum 7G and bringing the typewheel back to its initial position with the hub 71 rest-ing against the vertical stop 71. -This release of the ratchet- 81 is effected by the mechanism new to be described.

Below the rear end of the paw] 95 is a 96 (Figs.M 2, 5 and 6) fast to a shaft l i andcai'rying-on Vthe outsdeof plate 1 an upwardly extending nrm 98 having n shoul sh H yided .w ith"afsinall lever V100 arranged to en- 4 gadethefslionlder or stop on jarln 98.

."lfifhen, however, the arln 61 is raised by magnet. 5S, as shown in Fig; 5, the rear end of the lever is depressed against the top of the ann 98. If now the magnet 66 (which 'it will be' .remembered mnstactua'te its arma before `magnet-58 can work) bede 's cillatedbymagnet 66,), ,is- -i Wfrdlyyas 'at 99.5 'and is 4proenergized 'it-'Will permit 4the spring 69 to 4throw the arm 99 forward and with it the lever 100, thus permitting the rear end of the latter to he depressed by the spring rod 101l into' engagement with the shoulder or stop on arm 98. 0n energizing the magnet 66 again, the arm 99 reti-acts the lever 100 and arm 98 to the positions shown in Fig. 6, thus disengaging awl 95 from the ratchet 8l as previousl ascribed. On the end of the sha-ft 97 a jacent to plate 2 is an upwardly extending arm 192, carrying at its top a lever 103 the rightend of which (see Flgs. 7 and 8) lies in iront of the pawl 82. The arm 102 is loose on its shaft, and is held yieldingly against a. stop 104, xed 0n the shaft, by the pressure of the paw'l on the lever 103. It will now be seen that. when the shaft 97 is rocked to withdraw pawl 95 from the ratchet 81 it. will also throw the arm 102 backward and, through the instrumentality of the small lever 103, disengage the pan-'1 S2 also. Thus both Pan-'ls are dis engaged; and the sha-ft 78 being free, it is instantly rotated by the springs 86 and 92,

winding up the cord 72 and drawing the typewheel back to its initial position. On dencrgizing magnet 66 after the operation just. described, the parts associated with shaft 97 are restored to normal osit-ion by a coil spring 97, urging said smit in the clockwise direction. One end of this spring is fast to the shaft, while its other end, depending below the shaft, is held rearwardly under tension by a cord 9T", Wrapped around a winding stud 97c by which the tension of the spring can be regulated.

As previously explained, magnet 66 cannotoperate its associated mechanism unless magnet 3S be also energized, and hence the latter magnet must be energlzed during the operation of retract-ing the typewheel. But

The speed of the last-mentioned shaft will of course be correspondingly reduced; but this is no drawback, since the unwinding of the springs, necessary to rotate the friction disks through an A angle sniiicient for the line-spacing, is very slight. Moreover, the springs are rewolmd at each tra-vel of the typen-'heel to the end of a line, so that they are ren-ouml after cach movement of the paper. The s rings nre prevented from nnwinding by tie friction of the paper, held against the friction disks by the cramp disks, tho aper itself being prevented from unwinnling off the roll by suitable mechanism not shown. The preferred mechanism for the purpose is described and claimed 1n prior patents of the said John Burri', dcceased, (Nos. 7349.97 and 754420, dated July 21, 1903, and March 15, 1904, respectively),

The keys being normally in electrical, contact with the upper bars it will be clear that on depres- .$101.1 0f key .C 0f.

Thus current[impulses in ,either direction can be sent over the circuits ,simultaneously or -in any-desired order of succession .accordingto the order in which the keys are depressed.

,The Operation of the machine will now be readily understood, The first function to be performed is the rotating of the typewheel to bring to the printing point the pair of characters containing the character which it is desired to print. For this purpose alternate positive and negative impulses are sent over circuit A, as by alternate depression of keys C and D', until the rotation of the typewheel, in the manner described, brings the selected pair of type to the printing position. While the key (C or D) last employed is kept depressed (thereby energizing magnet 66 but not actuating its armature, since, as previously explained, this magnet cannot operate until its armature load is partially relieved by the action of magnet 38) one or the other of keys E, F is depressed thereby causing an impulse ot corresponding polarity t0 be sent over circuit B. Which of these keys is depressed depends upon whether the letter to be selected from the pair at the impression point is above or below the laten. Thus, if a positive impulse will energlze the polarized ma met 33, and hence cause the shiftinfr mem er to be lowered, depression of key E will result in the character below the platenbeng brought to the printing ositlon. Similarly, depression of key F w1l l, by sending a negative impulse and energizing polarlzed magnet 84 cause thc shifting member 25 to be lifted and the .i vchu'rasterlububttllcplutehyto be. brought to 1 position.- z: '-lfhcscanugnets being quiclcc'wtlug 'thel'sbifting-ineu'lbcr Vis set before magnets Vtlandli-cuu y'be Vfully energized.

Thereupon magnet 58, 4fully energized like the rest,'draws flown its armature 59, which raises the pawl 57 and so actuatcs the platen. The parts are now in the positions shown in Fig. 5. On breaking the circuits no eiiect is produced on the tongue 13, since the magnet 16 is polarized and hence the tongue ,remains .against Y whichever zpoleA it came. tol rrest on'. The denergization of magnet' 66, however, permits the spring 69 .to restore 4t'he-arn-iature G5 to its initial posit-ion, as shown in Fig. 2, while the deenergization of magnet 38 retracts. the shift-- ing 4finger 24, thus freeing the typewheel, and depresses the pawl 82, thereby rotating the shaft 78 and advancing the typewheel one letter-space. The upward movement of the armature 3T, under the influence of spring 43", raises armature- 59, whereupon the arm 62 is rengaged with the stop 63. The parts are thus restored to their initial positions, as shown in Figs. 2 and 4.

The printing wheel may be returned to its initial position from any point in its line of travel, after any printing operation, the parts then being, as previously stated, in the positions shown in Fig. 5. The circuit of magnet 6G is now broken, allowing the armature 65 to be retracted and therefore causing the lever 100 to en age the shoulder on arm 98. The circuit 1s now closed again, whereupon the armature is actuated and through the instrumentality of the lever named throws the arm 98 rearward, thus disengaging pawls and 95. The shaft 78 being treed the springs 86 and 92 revolve the shaft and wind up cord 72- on its drum.
